Magnetic Optical Rotation from Real-Time Simulations in Finite Magnetic Fields

Benedicte Sverdrup Ofstad, Meilani Wibowo-Teale, Håkon Emil Kristiansen +8

We present a numerical approach to magnetic optical rotation based on real-time time-dependent electronic-structure theory. Not relying on perturbation expansions in the magnetic-f…

Transient spectroscopy from time-dependent electronic-structure theory without multipole expansions

Einar Aurbakken, Benedicte Sverdrup Ofstad, Håkon Emil Kristiansen +5

Based on the work done by an electromagnetic field on an atomic or molecular electronic system, a general gauge invariant formulation of transient absorption spectroscopy is presen…

Adiabatic extraction of nonlinear optical properties from real-time time-dependent electronic-structure theory

Benedicte Sverdrup Ofstad, Håkon Emil Kristiansen, Einar Aurbakken +3

Real-time simulations of laser-driven electron dynamics contain information about molecular optical properties through all orders in response theory. These properties can be extrac…

Linear and nonlinear optical properties from TDOMP2 theory

Håkon Emil Kristiansen, Benedicte Sverdrup Ofstad, Eirill Hauge +4

In this work we present a derivation of the real-time time-dependent orbital-optimized Møller-Plesser TDOMP2 and its biorthogonal companion, time-dependent non-orthogonal OMP2 (TDN…
